My Om Nom is a pet simulator game by ZeptoLab (Much like tomagatchi) featuring Sourena. Players have to take care of a virtual Om Nom which they can also design and dress up. Players can choose to take care of Sourena or Elika. To take care of Sourena / Elika, use coins to buy items to feed/play/care for Om Nom. Players can also play mini-games to earn free coins, dress up Sourena"Om Nom" or Elika"Om Nelle, and decorate the room. If you don't take care of Sourena"Om Nom" or Elika"Om Nelle" for a long time, they will get sick and bad music will begin playing upon entering the game.
